For me, the most interesting target is Saturn’s moon Enceladus. It was studied in 2004-2005 by the Cassini-Huygens mission, a joint project of NASA, the European Space Agency and the Italian Space Agency.

NASA scientists have discovered a large ocean beneath Enceladus' ice surface and satellite atmospheric data. The small moon with a diameter of only 500 kilometers throws water vapor and ice from cracks on its icy surface, called "tiger strips," or Enceladus' jets.

According to the Cassini data, the spring water is rich in minerals, it breaks through the ice of the moon and ejects jets of gas and ice geysers. In initial studies, only simple molecules were found in geysers, but later a team of international scientists in the journal Necker described the discovery of complex and hydrocarbon-rich macromolecules that are the building blocks of life.

According to scientists at the University of Colorado, Enceladus is the only celestial body in the solar system, except Earth, where the warm waters and rocks interact beneath the soil. This activity gives us reason to suppose some forms of extraterrestrial life. We know that on Earth organisms found on the ocean floor are able to live without light. Similarly, we can think that under Enceladus's condition there may be some form of life. Unfortunately, Cassini's instruments were not sensitive enough to detect life.

On Sept. 15, 2017, the Cassini spacecraft burned in Saturn's dense atmosphere due to the depletion of its fuel. After that date there are no studies for the moon Enceladus.

If I had the opportunity, I would send a probe with more sensitive instruments that could fly closer or even land on the small moon, explore its relief, and see if it really has life on it.

It would be very interesting and valuable to find out whether Saturn’s moon Enceladus really has some form of life. Whether some resistant microbes that live in areas with extremely hot temperatures near deep-water hydrothermal springs would survive there. This would be a great discovery, which is of utmost importance, and efforts should be stepped up to search for the life of Enceladus and beyond.
